Nami: Heart, BPM, HRV & Breath

🫀 Nami: Heart, BPM, HRV & Breath
Advanced HRV and heart rate analysis. Monitor breathing with accuracy.
Nami is a high-precision tool for monitoring heart rate, HRV, and breathing—validated in academic research and designed for athletes, therapists, health professionals, and wellness enthusiasts.

No external hardware is required. Nami uses built-in microphones or compatible Bluetooth heart rate monitors to capture physiological signals and deliver real-time insights.

❤️ Key Features
📈 Real-time heart rate and RR interval monitoring
🧠 HRV metrics: RMSSD, SDNN, LF/HF, spectral analysis, coherence
🌬️ Breathing trainer with customizable pacer and HRV targets
🧘 Biofeedback tools for relaxation and stress reduction
📊 Zoomable graphs with pinch and tap-to-read interaction
📁 Export data to CSV or share via messaging and social apps
🧪 Research-level precision and full signal visibility
👥 Multi-user profiles on the same device

🔬 Research-Grade Accuracy
Nami results from years of experimentation and validation in university labs.
It uses phonocardiographic methods—measuring heartbeats via microphone—to detect RR intervals with high temporal precision.

⚠️ The camera method is experimental. Accuracy may vary by device and condition. For best results, use the microphone or a Bluetooth HR strap.

🎮 Breathing and Biofeedback Modes
Visual guides with millisecond pacing
Modes: Pacer (with graph) and Game (timed without distractions)
Ideal for HRV biofeedback, relaxation, and coherence training

🏋️‍♂️ For Athletes, Therapists & Researchers
Nami is used in:
• High-performance sports
• Biofeedback therapy sessions
• Academic cardiovascular and psychophysiology research

🔧 Hardware Compatibility
🎤 Built-in microphone (recommended)
📱 Experimental camera mode for light-based HR detection
⌚ Bluetooth 4.0 / BLE sensors, such as:
Polar H6, H7, H10, H01
Wear OS smartwatches with supported HR profiles

📘 Quick Start Guide
1. Choose sensor (mic, Bluetooth strap, or Wear OS)
2. Start a session (Pacer or Game)
3. Sit still, breathe naturally, and let Nami read your rhythms
4. Explore graphs and export your data if needed

Do not press too hard on sensors. Movement may reduce signal quality.
